In filling mattresses the material of whatever character it is, mustbe free from dust and it must also be it will not be fed into the shredded so that mattress in lumpy condition. Various machines have been devised for this purpose but for various reasons none of them factory. The machine,

have devised we believe ical improvement on has proved entirely satishewever, which we to be a-great practhose which have heretofore been constructed in that it is capable of thoroughly separating the filling machine as many timesas is desirable and finally filling the mattress by blowing the filliiig into a;

Our invention willbe understood by reference to the drawings in which itis shown in its preferred form.

a ball-bearihg mechanism of ordinary construction which rests against the under'surface of the perforated plate 5. v On this shaft and a ball-bearing collar 11 plate 12 having thereon tween which and the collar above the platen is on which rests the another collar 13 be- 1 1 the plate 12 is clamped so that the rotation of the shaft 8 willca-rry with 8 is set 1n a socket casing 15 mounted on'the stand 16.

This shaft 14; in the bottom of a On the bevelled gear '17 to by a second bevelled aft 19 and operated nning. over a pulley on the shaft 19 and a second pulley on the shaftv 21 of the motor 22. i On. the plate 12 are mounted four arms 23 each carrying a series of fingers 24: and above them other fingers 25 are mounted in staggered relation thereto,'these last. fingers being mounted upon a spider frame 26, the arms of: which are carried by a plate 27 and collar. 28' in which the shaft 8 turns. 29 is an oil cup to lubricate the shaft. The outer ends of the spider frame 26 are attached to the interior surface of the casing r at 30. i i

From the above it will be understood that while the spider carrying the fingers 25 is stationary, the spider23; carryingthe fingers 24, is rotary and .as' the fingers of the rotary spider are quite close to the fingers on the stationary spider any materialfedinto the chamber containing the spiders will be torn and shredded to a considerable extent and the the chamber within the casing 4 by a pipe 34i'and the fan is rotated to cause the air and material which has been drawn into it to be forced. out through the pipe 35 in the direction "of the arrow. The pipe 35 connects with a three waycoupling 36 the lower edge of: which has an opening connecting with the pipe 7 while the third opening is connected with a pipe 37 which leads to the mattress. The opening between the coupling 36 the pipe'87 is controlled by, a damper 38' which may be operated in any usual way. from the outside.

is a hopper into which the filling material is fed by hand. It will be noted that this, hopper has at the bottom perforations 41-0 and that the casing 4: is perforated as at 41. The casing also has a' shelf 42; to which is pivoted a damper 4:3 capable. of resting in either oneofj two positions, as shown in Fig. 2 wherethe" damper 43 is. in filling position, that is tdsayfthe machine is in condition to be filled through the mouth of the hopper the filling. material striking the damper 43 and sliding down towards the casing. When the casing has had a suf'iicient load of filling the damper 43 is turned up into the position shown in dotted lines so that no more filling can be put into it.

As shown in Fig. 2 the apparatus is in position to be filled. It is understood that at this time the blower 32 is active to withdraw air from the casing this air being furnished through the perforations and 41 in the lower part of thehopper. At this time also as shown in Fig. 2 the damper 38 is closed so that there is a circulation from the casing through the pipe 34, fan 32, pipe 25 and collar 7 back into the casing. The motor 22 is started and the spider 28. is rotated so that the material as it is fed into the casing is torn by the cooperation of the moving fingers 24 and the stationary fingers 25.

When the casing is sufiiciently full the damper 43 is closed into its dotted position and the filling is drawn out through the pipe 34 and back through the pipes 35 and 36 and pipe 7 and thus circulated until such time as it is considered that the material has been properly treated. To inspect the condition of the material a door 44 which may be of glass is provided in the upper part of the casing. Experience shows when the proper amount of tearing Or shredding has been given to the material. lVhen the process is finished the damper 38 is thrown down as shown in dotted lines in Fig. 2 thus substantially closing the passage to the pipe 7 and opening the passage to the pipe 37. The fan 32 continuing its operation draws the material out of the casing and delivers it into the pipe 85 through which and the coupling 36 it is delivered to the pipe 37 and from it passes to the mattress.

To attach the mattress to the pipe we have preferred to use a clamp such as is shown in Fig. 4 (see also Fig. l) where 46 is a bracket to which is pivoted two segments 47 and 48. The free ends of these semiannular pieces have lugs 49 and 50. The lug 49 has pivoted thereto an arm 51 threaded at its free end and setting into a slot end of the lug 50. 52 is a sleeve which is on the arm 51 and 53 is a winged nut on the arm 51 by which the ends of the segments 47 and 48 may be drawn towards the lug 49. A slit in the mattress is placed over the end of the pipe 37 in the usual way and the clamp 47, 48 is passed around it as shown in Fig. 1 and the lugs 49 and are then clamped'together as closely as possible by means of the winged nut 53. 54 is a handle on the end of the screw 51. As shown in Fig. 1 the end of the pipe -37 is spread or formed into a collar as at 371 to assist in making a good, air-tight joint at this point.

It will be readily seen that the details oi the construction of this machine may be otherwise than as shown and described above. We believe, however, that in its present form our invention is embodied in a construction which is simple to manufacture and is capable of very satisfactory use.

What we claim as our invention is z 1. In a machine of the kind described, a rotary member mounted on a vertical shaft and a stationary member, each member hav ing fingers, the fingers on the rotary member being arranged in staggered relation to the fingers on the stationary member, a casing containing said members, and having a delivery opening for said material and a separate delivery means for the dust falling therefrom, and means for causing the material to be shredded to pass between said fingers whereby said fingers will tearand separate said material and cause it to de liver dust and dirt to said delivery means and allow said material to be drawn off through said delivery opening.

2. In a machine of the kind described, a rotary member mounted on a vertical shaft and a stationary member, each member having fingers, the fingers on the rotary member being arranged in staggered relation to the fingers on the stationary member, a casing containing said members, and means for causing the material to be shredded to pass between said fingers, and means comprising a fan and an opening in said casing and connections between said fan and said opening whereby said fan will draw such material from said casing and a separate delivery means adapted to allow the separate collection of the dust and dirt falling from said material.

A machine of the kind described comprising a casing having mounted therein a stationary member mounted on a vertical shaft and a rotary member, each member having fingers, the fingers on the rotary member being arranged in staggered relation to the fingers on the stationary memher, said casing having a perforated false bottom forming a chamber below it to receive dust, said chamber having a clean-out door.

5. A machine of the kind described comprising a casing having mounted therein means for shredding material fed thereto, an inlet hopper on one side thereof, a delivery opening at the other side, an exhaust fan and connections with said deliveryopening,
